b25bb230cd Removed apiutils.h and related cleanup. 
ExtensionConfiguration is just a simple container for extension names
(in a perfect world we would use vector<string> and range-based for
loops), and HandleScopeData was in the totally wrong place. Some
additional cleanup on the way, e.g. using the null pattern behind our
external API.

bc9bc0de1a Fix handle zapping interaction with NoHandleAllocation. 
This makes sure that closed handle scopes are properly zapped even if an
enclosing NoHandleAllocation shrunk the limit. It also unifies the code
that performs scope closing for internal and external handle scopes.

fb6776e84a Made Isolate a mandatory parameter for everything Handle-related. 
Unified parameter order of CreateHandle with the rest of v8 on the way. A few
Isolate::Current()s had to be introduced, which is not nice, and not every place
will win a beauty contest, but we can clean this up later easily in smaller steps.

3c22524119 Avoid handle dereference during graph optimization. 
With parallel recompilation enabled, objects made accessible by handles may
have changed between graph construction and graph optimization. Therefore
we must not assume that information on those objects remain the same between
those two phases. To police this, we forbid handle dereferencing during
graph optimization.
Exceptions to this rule are:
 - Dereferencing the handle to obtain the raw location of the object. This
   is safe since parallel recompilation acquires RelocationLock
 - Some places that dereference the handle for a type check. These are checked
   to be safe on a case-by-case basis.

30a0a7de43 Split nested namespaces declaration in two lines in accordance with C++ Style Guide. 
This issue was raised by Brett Wilson while reviewing my changelist for readability. Craig Silverstein (one of C++ SG maintainers) confirmed that we should declare one namespace per line. Our way of namespaces closing seems not violating style guides (there is no clear agreement on it), so I left it intact.

e718576d4f Split handle scopes into an internal version and a version accessible 
through the API. This allows us to verify state on entry through the API.
In this change verification in the API entry is checking that the current
thread holds the V8 lock when a HandleScope is instantiated if a v8::Locker
has ever been used by the V8 instance.
